2 0 all whomit may concern;

Beat known that I, CHARLES F. HINKLEY, a citizen of the United States, residing at Seelyvi lle, inthe county-of Vigo and State of Indiana, have invented certain new andchines that have swinging cranes or booms on which auxiliary engines are mounted for operating machinery connected with shovels or scoops for assisting in' the operation of the shovels or scoops, the invention having reference particularly to mechanism that is adapted to enable the engineer who may control the main ei'igines to also operate the auxiliary engines of the crane, the invention having reference also to means whereby the engineer may cause the bottom of the shovel to he released for dumping the load.

Heretofore it has been customary to employ and station a man -on the swinging crane for operating the auxiliary engine or engines thereon and for dumping the loads out of the shovel; and the ob jcct of the present invention is to provide means whereby the auxiliary engine may be operated and controlled by the engineer who controls the engines for hoisting the load and swinging the crane, thus obviating the necessity of employing an additional attendanton the crane, further objects being to provide mechanism that will enable the engineer lo have complete control of all movement of; the shovel or. similar apparatus, so hat the greatest efficiency andeconomy in the operation of the machine may be attained.

The invention comprisesmechanism that extends from the position of the engineer to the auxiliary engine that moves, on the swinging crane. for starting or stopping the means at the engineers position for auxiliary engine, the mechanism being self adjusting during swinging motions of the crane. And theinvention comprises also a fluid actuateddevice for releasingthe bottom of the shovel for dumping the load -and -con trolling the operation of "the device. -And the invention consists further in the parts Pa.tented Oct. 13, 1908.

and combinations and arrangements of parts as hereinafter particularly described and de-. fined in the appended claims.
